Abstract

PURPOSE: A disc brake system is provided to keep clean the surface of a disc and a pad with a self-cleaning device. CONSTITUTION: A disc brake system consists of a ventilated type disc(4) rotated by an engine; a caliper(6) fixed to a vehicle body from the outside of the disc; a pressurizing device pressurizing the disc with brake hydraulic pressure; and a self-cleaning device guiding air flow to the surface of brake pads(8,9) and the disc. The disc brake device generates impurities while pads are contacted with the disc in case of a braking. Then, the disc is rotated to generate air flow through a ventilating hole(2). The part of the air flow moves along a left and a right passage(14,18) through an air inlet(12). Air flow along the left passage is injected to the right side of the disc and the surface of the pad(8) through a nozzle(16) to remove impurities.

[산업상 이용분야][Industrial use]

본 발명은 자기 청정수단을 구비한 디스크 브레이크 장치에 관한 것으로서, 보다 상세하게는 디스크와 브레이크 패드 사이에서 발생하는 이물질에 의해 제동력이 저하되는 것을 방지할 수 있도록 한 자기 청정수단을 구비한 디스크 브레이크 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc brake device having a self-cleaning means, and more particularly, a disc brake device having a self-cleaning means capable of preventing the braking force from being lowered by foreign matter generated between the disc and the brake pad. It is about.

[종래 기술][Prior art]

차량의 브레이크 장치는 주행하는 차량을 감속하거나 또는 정차시키는 장치로서, 그 구조는 회전체를 고정체에 가압하여 회전체의 속도를 줄이는 것으로 이루어진다.A brake device of a vehicle is a device that decelerates or stops a running vehicle, and its structure consists of pressing the rotating body against the stationary body to reduce the speed of the rotating body.

이러한 브레이크 장치는 드럼 브레이크 식과 디스크 브레이크 식으로 구분되고 있는데, 드럼 브레이크 식과 비교하여 볼 때 디스크 브레이크는 디스크가 거의 노출되어 있으므로 방열작용이 좋고 페이드 현상이 잘 일어나지 않는 장점이 있다.The brake device is divided into a drum brake type and a disc brake type. Compared to the drum brake type, the disk brake has an advantage that heat dissipation is good and fading does not occur because the disk is almost exposed.

그리고 디스크가 열괭창을 하는 경우에도 패드의 클리어런스는 거의 불변이므로 브레이크 페달을 밟아도 남는 간격이 감소하지 않는 장점을 갖는다.In addition, even when the disc is in the hot shoe, the clearance of the pad is almost unchanged, and thus the remaining space is not reduced even when the brake pedal is pressed.

게다가 드럼 브레이크에서 일어나는 셀프 서보작용이 없으므로 좌우 제동력의 차이도 적고 편 제동도 잘 일어나지 않는 장점이 있다.In addition, since there is no self-servo action in the drum brake, there is a small difference in the left and right braking force, and the braking does not occur easily.

이러한 우수한 기능으로 대부분의 고급 승용 차량에는 디스크 타입의 브레이크를 적용하고 있다.Due to this excellent feature, most high-end passenger cars use disc brakes.

이러한 디스크 타입의 브레이크는 디스크가 회전하는 동안에 브레이크 패드가 이 디스크의 측면에 마찰 접촉할 때 이들 사이에는 마모분진이 발생하고 또 대기중의 이물질이 열에 의해 달라붙는 현상이 나타난다.This type of brake has a phenomenon in which wear dust is generated between the brake pads and the side surfaces of the disk while the disk rotates, and foreign matter in the air sticks to each other by heat.

이러한 이물질들은 제동시 패드가 디스크에 접착하는 가압력을 저하시키게 되므로 제동이 저하되는 문제점을 야기시킨다.These foreign matters cause a problem that the braking is lowered since the pressing force that the pad adheres to the disk during braking decreases.

The caliper 6 is shown with a pad 4 for pressing the sides.

상기한 캘리퍼(6)에는 패드(8)(9)를 전후진시키기 위한 피스톤(10)이 내장되어 브레이크 유압에 의해 작동할 수 있도록 되어 있다.The caliper 6 is provided with a piston 10 for advancing the pads 8 and 9 forward and backward to operate by brake hydraulic pressure.

상기한 디스크(4)에 형성된 통기공(2)과 상응하는 캘리퍼(6)의 내측면에는 공기 유입구(12)가 형성되어 자기 청정수단을 형성하고 있는데, 이 공기 유입구(12)는 좌우측으로 분리되어 우측 통로(14)는 패드(8)와 디스크(4)의 우측면 사이로 연통하고 있다.An air inlet 12 is formed in the inner surface of the caliper 6 corresponding to the vent hole 2 formed in the disk 4 to form a self-cleaning means, which is separated into left and right sides. The right passage 14 communicates between the pad 8 and the right side of the disc 4.

이 우측통로(14)의 끝단부에는 노즐(16)이 형성되어 공기를 큰 압력을 분사할 수 있도록 하고 있다. 이 노즐은 통로의 형상을 노즐형으로 하거나 별도의 노즐을 설치하는 구조를 모두 채택할 수 있다.A nozzle 16 is formed at the end of the right passage 14 so that a large pressure can be injected through the air. This nozzle can adopt both the structure of a passage shape as a nozzle type or the structure which installs a separate nozzle.

그리고 좌측통로(18)는 패드(9)의 중심부에 뚫려진 구멍(20)과 연통하는 구조로 이루어진다.(제3도 참조)The left passage 18 has a structure in communication with the hole 20 drilled in the center of the pad 9 (see FIG. 3).

제4도는 상기한 패드(9)의 사시도로서 좌측통로(18)가 연통하는 구멍(20)이 뚫려져 있으며, 이 구멍(20)의 끝단부로부터 방사상으로 연장되는 다수개의 분산로(22)가 형성되어 있다.4 is a perspective view of the pad 9 described above, in which a hole 20 through which the left passage 18 communicates is opened, and a plurality of dispersion passages 22 extending radially from an end of the hole 20 are provided. Formed.

이와 같이 이루어지는 본 발명의 자기 청정수단을 구비한 디스크 브레이크 장치는, 제동을 하는 경우 패드(8)(9)와 디스크(4)가 마찰 접촉하면서 주위의 먼지들과 함께 많은 이물질을 이곳에 발생시키게 된다.The disc brake device having the self-cleaning means of the present invention, which is constituted as described above, causes the pads 8 and 9 and the disk 4 to frictionally contact with each other to generate a large amount of foreign matter here. do.

이때 발생하는 이물질이나 먼지 등은 패드의 표면과 디스크의 표면에 붙게 되는데, 차량이 주행중 회전하는 벤틸레이티드형 디스크(4)는 통기공(2)에 의해 디스크 외측으로 공기의 흐름을 만들면서 냉각작용을 하게 된다.At this time, foreign matter or dust generated on the surface of the pad and the surface of the disk are adhered. The ventilated disk 4, which is rotated while the vehicle is running, is cooled by making air flow out of the disk by the vent hole 2. It works.

그리고 상기한 공기의 흐름중 일부는 캘리퍼(6)에 형성된 공기 유입구(12)로 유입되면서 각각 좌우측 통로(14)(18)를 따라 이동하게 된다.Part of the flow of air is introduced into the air inlet 12 formed in the caliper 6 to move along the left and right passages 14 and 18, respectively.

이때 좌측통로(14)를 따라 흐르는 공기는 노즐(16)을 통하여 패드(8)의 표면과 디스크(4)의 우측면으로 힘있게 분사된다.At this time, air flowing along the left passage 14 is strongly injected through the nozzle 16 to the surface of the pad 8 and the right side of the disk 4.

이 공기의 분사에 의해 이곳에 끼어있는 이물질은 제거되고, 또 좌측통로(18)로 흐르는 공기는 패드(9)의 구멍(20)을 따라 나오면서 이 구멍의 끝단에서 방사방향으로 형성된 분산로(22)를 따라 패드(9)의 전체 표면에 분사되는 효과를 얻을 수 있다.The foreign matter trapped therein is removed by the injection of air, and the air flowing into the left passage 18 flows out along the hole 20 of the pad 9 and is formed radially at the end of the hole. ), The effect of being sprayed on the entire surface of the pad 9 can be obtained.

따라서 이 부분의 이물질도 동시에 제거할 수 있다.Therefore, foreign substances in this part can be removed at the same time.

[효과][effect]

이상 설명한 바와 같이 본 발명에 의한 자기 청정수단을 구비한 디스크 브레이크 장치는, 차량 주행중에 벤틸레이티드형 디스크에서 발생하는 냉각 공기의 일부를 패드 표면과 디스크 표면측으로 유도하여 분사할 수 있도록 하고 있기 때문에 제동중 발생하는 이물질을 제거할 수 있어 이물질 누적에 따른 제동력 저하를 방지할 수 있다.As described above, the disc brake device provided with the self-cleaning means according to the present invention allows a part of the cooling air generated by the ventilated disc to be guided to the pad surface and the disc surface side while driving the vehicle. Since foreign matters generated during braking can be removed, the braking force can be prevented from being accumulated.
